Add spaces: When generating image sequences, clicking the Add Spaces checkbox
causes extra spaces to be added to the filenames to ensure that the sequence of files is
read in proper order by some other applications.
Advanced: The Advanced button is only active for QuickTime movies. Clicking this
button opens the standard compression settings dialog. In most cases, you should not
need to make any changes in this dialog.
Sample rate: Sets the audio sample rate for your exported movie. For best results, set
this to be the same sample rate as the source audio in your project.
Advanced: The Advanced button opens the standard Sound Settings dialog. In most
cases, you should not need to make any changes in this dialog.
Output Tab
The Output tab contains the following controls:
Use current project and canvas settings: When this is checked, this setting overrides
the contents of this dialog with the current settings in your project. This allows one
export preset to be used with multiple project presets. When this setting is turned off,
you can create specific settings for the export preset.
Resolution: You can specify the output size to be relative to the project’s frame size
(Full, Half, Third, or Quarter) or choose Custom and type a specific number into the
width and height value fields.
Color: Choose whether the exported items include the color data only, color data plus
alpha channel (transparency), or just the alpha channel data.
Note: Some compressor types do not support alpha channels.
Premultiply alpha: When this box is checked, semi-transparent pixels in your output
are mixed with the project background color (set in Project Properties).
Use field rendering: When this box is checked, the output always renders individual
fields regardless of the setting in the Canvas View menu. When not checked, frames are
rendered whole, regardless of the setting in the Canvas View menu.
Use motion blur: When this box is checked, motion blur is applied to moving objects
regardless of the setting in the Canvas View menu. When not checked, no motion blur
is applied.
